A day after the plaintiff's lawyer filed a motion to discontinue to the sweatshop suit in Queens, Wang's lawyer Hugh Mo fired off a letter threatening legal action if the motion wasn't filed with prejudice.

Filing with prejudice would prevent new lawyers from being able to refile in federal court or anywhere else.

But lawyer Ming Hai isn't backing down and calls Mo's letter is against the law as well as "blatant intimidation". He told New York Magazine:

"It is illegal to retaliate against an employee and their family, friends, and legal representatives for filing a claim [like this]. Under section 740 of New York State human rights law, a former employer… cannot retaliate by threatening the employees who filed the complaint, or the lawyer."

Upon hearing Hai's comments, Mo summed up his letter as this:

"It appears that there is no factual or legal basis for the lawsuit, and that the lawsuit appears to be frivolous, particularly in relation to the allegation that Alexander Wang's business is a sweatshop."

In fact, the 200 square foot "sweatshop" Hai mentions in the lawsuit is actually a spacious 4,000 sqft. work room with ten-foot windows.

And then there's this.

Last week Ming Hai had to pay Hugh Mo $5,000 and a written apology for misconduct in a $1.8 billion lawsuit on behalf of former Chinese gymnast Sang Lan. Mo adds he thinks Hai dropped the case against Alexander Wang because he was scared to go up against him in court again.
